You have a 0.025 L solution of piperazine (perhydro-1,4-diazine), a weak dibasic base. The Ka values for its conjugate acid are 4.65*10-6 and 1.86*10-10 (in a solution with an ionic strength of zero). You would like to know the concentration of your solution and decide to titrate with HCl. You make a 0.10 M solution of the acid and use methyl orange as an indicator. You reach the endpoint after adding 54.16 mL of your HCl solution. (c) How many...
Dont need (a) or (b) thank you
